I feel that a few new sections should be added to the comps file:
Scanner Support
CD-Writing Support
Digital Camera Support
In particular there should be sections for software which only makes sense
if you have the corresponding hardware (like scanners, cdrw, etc.)
If you don't have the hardware you probably don't want to
install the software.

What we are currently trying to do is to make the groups as self-containing as
possible, to add these as specific groups in comps will be the opposite of that.
While I understand why you are asking for this, the solution that we will have
will be considerably different than what comps has been in the past. Keep an eye
on future betas to get an idea of what we are aiming for.
